    • Systems, methods, and other embodiments associated with selective notch filtering for howling suppression are described. According to one embodiment, an apparatus includes a howling detector that detects howling by performing a time domain analysis of speech signals to identify a speech signal that may be exhibiting howling and performing frequency domain analysis to confirm that the speech signal is exhibiting howling. The apparatus also includes a suppression selector configured to select a suppression technique, a signal processor configured to process the speech signal according to a selected suppression technique. The apparatus outputs, without suppression-related processing, speech signals that are not identified based on the time domain analysis. In another embodiment a method includes analyzing a speech signal to detect howling and when howling is detected, selecting, based on the howling analysis, a howling suppression technique from a set of howling suppression techniques that includes at least two different howling suppression techniques.

    • A lid operation arrangement of a container includes an automatic operated unit for automatically operating a lid panel, a foot operated unit for manually operating the lid panel, and a motorized unit operatively linked with the automatic operated unit and the foot operated unit. When the motorized unit is activated by the automatic operated unit, the motorized unit is arranged for generating a torque enhancing force to move the lid panel from the opened position to the closed position and for generating a decelerating force to move the lid panel back to the closed position from the opened position in a hydraulic manner. After the lid panel is lifted up to the opened position by the foot operated unit, the motorized unit only generates the decelerating force to move the lid panel back to the closed position from the opened position in a hydraulic manner.

    • Provided are methods and systems for video data processing. In an exemplary system, there is a video source and a display unit. The display unit may receive video data from the video source and display it at a first refresh rate. The video source may cause the display unit to enter a power economy mode, in which the displayed video is static. In this mode, the video source stops sending new video data, while the display unit selectively stores one or more of the previously received video frames and further displays it repeatedly at a second refresh rate, which may be lower than the first refresh rate (e.g., it may be decreased from 60 Hz to 40 Hz). In the power economy mode, the power consumed may be decreased by about 10-20% for both the video source and the display unit in some embodiments.
    • 提供了用于视频数据处理的方法和系统。 在示例性系统中,存在视频源和显示单元。 显示单元可以从视频源接收视频数据并以第一刷新率显示它。 视频源可能导致显示单元进入电源经济模式,其中所显示的视频是静态的。 在该模式中,视频源停止发送新的视频数据,而显示单元选择性地存储先前接收到的一个或多个视频帧,并以第二刷新率重复地显示它,其可以低于第一刷新率(例如, ,它可以从60Hz降低到40Hz)。 在电力经济模式中,在一些实施例中,对于视频源和显示单元,所消耗的功率可以减少大约10-20%。
